AUTOMATIC DEVICE FOR OPERATINGVWHISVTLES.

SPECIFICATIN formigpart of Letters Patel lt No. 592,015, dated'october19, 1897.

Application filed June' 29. 1397.

To all whom 't may conccrm V Be it known that I, HENRY C. MUSTARD, acitizen of the United States, i'esidingat WVest Point, in the county ofTippecanoe and State of Indiana, have invented'certain new and usefulImprovements in Automatic Devices i for Operating Whistles, of whichthefollowtinue to sound until purposely disengaged by the fireman orengineer, thus insuring that a warning shall be given as long before thelocomotive passes such a point as may be deemed proper, and also nsuringa continuous sound as long as may be desired.

An apparatus enbodying my said invention, as applied tolocomotive-engines, will be first fully described and the novel featuresthereof then pointed out in the claim.

Referring to the accompanying drawings, which are made a part hereof,and on which similar letters and numerals of reference indicate similarparts, Figure 1 is a side elevation of a loeomotive provided withapparatus embodying my said invention Fig. 2, a detail View, on aconsiderably enlarged scale, illustrating the Construction more clearly,as seen from the dotted line 2 2 in Fig. 3; Fig. 3, a transversesectional View showing another View of said apparatus, and Fig. 4 adetail diagrammatic View illustratin g an alternative Construction.

In said drawings. the portions marked A represent the locomotive; B, therailwaytrack; C, a strike located alongside said track; D, a baror'lever mounted on the locomotive and adapted to be operated bysaidstrike;

E, the whistle, and F the rod for Operating said whistle.

The locomotive, track, whistle, and rod for Operating the same of courseare or may be of any usual or desired Construction, and, not beingpeculiar'to my present invention, will not be further described herein,except incidentally in descrbing said invention.

The strike C is of a suitable form to oper- Serial No. 642305. (Nmodel.)

ate the bar or lever D. In order that itshall have a yielding character,so that the jar of the contact shall not be too'violent, I prefer tomake it of two parts, the upper or main part being supported on springss uponthe lower part, which in turn is secured upon the ties'T, as bestshown in Fig; 2. The said upper part is preferablyslotted, and the slotspass over pins c upon the sides of the lower part, which sides areinclosed by the edges of the upper part. The pins and slots connect thetwo parts together, while permitting a vertical movement of the upperpart upon the lower part, as will be readily understood.

The bar or lever D is shown in the princi- .pal views as pivoted at d tothe side of the fire-boX of the engine. It may be m ounted in anydesired manner which will enable it to operate the whistle when properlymoved. It has a foot or fioat D which comes in contact with the strikeO. This foot or fioat is so connected to the lever proper as to beadjustable in relation thereto, so that exactly' the desired amount ofcontact between said foot or fioat and the strike O can be secured.

The leverD is returned to position after the strike has been passed by aspring D attached thereto and to some suitable point on the locomotive.There is shown running from the top of this bar or lever a link 1,connected to a lever 2, whose other end is connected to a rod 3, whichin turn is connected to a lever 4:, which is connected, through a linkor chain 5, to the whistle-actuating rod F. A detent 4: on the sameshaft or pivot with the lever 4: is adapted to engage with a catch 6,and said catch is normally held forward by a spring 11. The bell-cranklever is pivoted at 7, the lever et at 8, and 'the catch 6 at 9, as bestshown. in Fig. 2. The link 3 has a spring 3 formed therein, and thisserves to take up some of the force of the movement and prevent tooviolent a pull on the whistle-rod. The usual handle F' is connected tothe end of the rod F, by which the whistle may be a 'sounded in theusual manner by hand by the fireman or engineer, and also, through thechain or link 10, be used to disconnect the catch 6, said catch beingnormally held into engagement by the spring 11.

The operation is as follows: When the locomotive in its course hasreached the strike IOO C,itope1'ates the bar or lGVGP D,Which,throughthe various connections, pulls on the Whistlerod F and sounds thewhistle. It at the same tine 'aises the end of the detent 4, so that itengages with the catch 0, and thus the whistlc is held open andcontinues to sound until said catch is drawn out of engagenent With saiddetent 4. The pivot S to the lever 4 is preferably in the form of ashaft or rod extending entirely through the cab for con- Venience inmaking the connections, as the 'od 01' lever D should be at the extremeone side of the loconotive, While the rod F and its handle 1 should nostConveniently be in the center, as shown.

Obviously, many other arrangenents of 'ods, levers, and links might beemployed to acconplish the same result and the pivots and connections belocated to suit the arrangenent adopted Without departing froni myinvention. I have shown one such ar'angenent in Fig. 4, in which bar Dis mounted in slides instead of on a pivot, while the level' 2 isstraight instead of angular, and the link l is dispensed with.

Having thus fully described my said invention, What I claim as new, anddesire to secure by Letters Patent, is

The combination, in an automatic appa'atus for soundinglocomotive-whistles, of a strike positioned adjacent to a railWay-track,a rod or lever suitably mounted on the locomotive and adapted to come incontact with and be operated by said strike, the whistle connectionsrunning from said rod 01' level' and adapted to operate said whistle, adetent carried upon a rock-shaft or pivot forming part of saidconnections, and a catch positioned adjacent to said detent and adaptedto en gage therewth, Whereby the Whistle may be held continuously openuntil pu'posely closed, substantially as set fol-th.

In Witness Whereof I have hereunto set my hand and seal, at Test Point,Indiana, this 19th day of June, A. D. 1897.

HENRY C. MUSTARD.
